Air Quality Sensor Market Report 2025

This Air Quality Sensor market report provides a comprehensive analysis of the market’s characteristics, size, and growth, including segmentation, regional and country-level breakdowns, competitive landscape, market shares, trends, and strategies. It also tracks historical and forecasted market growth across various geographies.

The air quality sensor market size has grown rapidly in recent years. It will grow from $5.65 billion in 2024 to $6.31 billion in 2025 at a compound annual growth rate (CAGR) of 11.6%. The growth in the historic period can be attributed to growing impact of climate change, ongoing research and development activities, the automotive industry’s need for in-vehicle air quality monitoring, increasing use of air quality sensors in educational research and projects, growing use of air quality sensors in agriculture.

The air quality sensor market size is expected to see rapid growth in the next few years. It will grow to $9.67 billion in 2029 at a compound annual growth rate (CAGR) of 11.3%. The growth in the forecast period can be attributed to increasing awareness of air pollution, regulatory standards and compliance, rapid urbanization and industrialization, rising health issues related to poor air quality, growing concerns about indoor air pollution. Major trends in the forecast period include innovations in sensor technology, development of smart cities and smart infrastructure, focus on environmental protection and monitoring, awareness and use of AQI for real-time air quality assessment, public health campaigns.

The increasing environmental pollution is expected to drive the expansion of the air quality sensor market in the future. Environmental pollution involves the contamination of air, water, or soil by harmful substances, which negatively impact ecosystems, human health, and the climate. This pollution is on the rise due to factors such as industrial growth, urbanization, and the extensive use of fossil fuels, which release more pollutants into the environment. Air quality sensors are essential in addressing environmental pollution, as they offer real-time data on pollutant levels, allowing for timely interventions and informed decision-making to reduce harmful effects on health and the environment. For example, in August 2024, a report by the United States Environmental Protection Agency (EPA) indicated that approximately 66 million tons of pollutants were released into the U.S. atmosphere in 2023. Thus, the rising environmental pollution is fueling the growth of the air quality sensor market.

Key companies in the air quality sensor market are developing advanced products, such as compact air quality sensors, to deliver real-time, precise air quality data with minimal space and infrastructure requirements. Compact air quality sensors are small, portable devices designed to measure and monitor air pollution levels, including particulate matter and gases, in real-time. For instance, in March 2024, Vaisala Oyj, a Finnish producer of environmental and industrial measurement products, introduced the Air Quality Transmitter 560 (AQT560). The AQT560 is a high-performance compact air quality sensor known for its wide detection range, covering PM1, PM2.5, and PM10, and its advanced calibration system and algorithms that ensure high accuracy and efficiency. It effectively measures aerosol particle concentrations from 0.3 to 10 microns, providing reliable detection of PM1 levels from sources such as traffic, residential wood burning, and wildfires, PM2.5 levels from long-range transport, and PM10 levels from activities like road dust, sandstorms, construction, and mining.

In January 2022, AccuWeather Inc., a US-based weather forecasting service provider, acquired Plume Labs for an undisclosed sum. Plume Labs will continue as part of the AccuWeather group, focusing on climate and environmental data, and aims to enhance its air quality forecasts for AccuWeather’s global audience of 1.5 billion people. The acquisition will also broaden its scope to cover a wider range of environmental risks, including climate and wildfires, and increase AccuWeather's investment in AI technology for improved weather predictions in response to climate change. Plume Labs is a French company specializing in air quality sensors.

An air quality sensor is a device that measures and monitors the concentration of pollutants and particles in the air to ensure safe and comfortable living and working environments. It detects various pollutants, such as CO2, VOCs, and particulate matter, and often integrates with data logging systems or real-time monitoring platforms to provide actionable insights and alerts about air quality conditions.

The main types of air quality sensors are signal-gas monitoring systems and multi-gas monitoring systems. A signal-gas monitoring system is designed to detect and monitor a single type of gas in an environment. It employs technologies such as non-dispersive infrared sensors, electrochemical sensors, and electroacoustic sensors. These systems are used to monitor various pollutants, including chemical, particulate matter, and biological contaminants, and are applied in settings such as restrooms, kitchens, living rooms, bedrooms, bathrooms, industrial plants, and more.
